Benefits of technology

[0012] The present invention has been made in an effort to provide a system and a method for regenerating a diesel particulate filter having advantages of enabling reuse of the diesel particulate filter.

Problems solved by technology

In addition, if the PM is excessively deposited on the diesel particulate filter, engine efficiency may be reduced since the exhaust system does not operate at full performance.
However, if the PM is excessively deposited on the diesel particulate filter, the engine speed may not be increased since the exhaust backpressure is excessively increased.
As a result, since the PM is not burned, the expensive DOC-DPF assembly becomes ineffectual so it must be replaced.

Abstract

A system for regenerating a diesel particulate filter of the present invention includes a fixing part, a fluid supplying part, a fluid inhaling part, and a controller. The fixing part fixes a housing of a diesel oxidation catalyst-diesel particulate filter assembly. The fluid supplying part supplies a fluid of high temperature and high pressure to a rear end of the housing. The fluid inhaling part inhales the fluid from a space between the diesel oxidation catalyst and the diesel particulate filter of the housing. The controller controls the fluid supplying part such that temperature of the fluid between the diesel oxidation catalyst and the diesel particulate filter arrives at a first predetermined temperature.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority to and the benefit of Korean Patent Application No. 10-2005-0122774 filed in the Korean Intellectual Property Office on Dec. 13, 2005, the entire contents of which are incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] (a) Field of the Invention [0003] The present invention relates to a diesel oxidation catalyst (DOC)-diesel particulate filter (DPF) assembly, and in particular, to a system and a method for generating a diesel particulate filter. [0004] (b) Description of the Related Art [0005] In general, a DOC-DPF assembly includes a housing, a diesel oxidation catalyst, and a diesel particulate filter, and the diesel oxidation catalyst and the diesel particulate filter are sequentially mounted in the housing with respect to an exhaust direction. Such a DOC-DPF assembly is mounted in an exhaust system of a diesel engine so as to remove air pollution material exhausting from the diesel e...
